7 '0 all Irma it may coat-era lie u; lrnown that L Josnrn: (l. E'lauicno, a citizen of Czechosiovairia, residing at i lewuric in the county of Essex and hitate oi NewJersey lnive invetcd certain new and usi-zitul lmprmcinents in l uii'flutting Machines, oi? which the 'l i illowing; is a spcciiication. v y

This invention relates to improvements in niarhines iorcutting fur and more particularly to that class of such machines which are designed for the purpose or cutting furs along zigzag lines it beingrthe practice to cut 'f urs in this manner so that when pieced logretl'u-nr the seams Will not be noticeable ironi the outer side.

its the skins of furs vary in thicknes nd in texture, it is one of the primary 0 nts o l thepresent invention to so constr i the machine that it will-be capable of acting upon various kinds of tors and evenly cut the same without the least liability of cansii'lg damage to the ture and es iiecially without liability of clipping the fur. An objec tion to some of the nrachines otlt' this class lies in the fact that the blades thereof are designed) to act with a shearing; cut so that while they may successtully out through the slrin oi the furs, they also clip the fur or hairs and llllUSllTllJ Lll' the quality of the iinal product, it being a well-recognized fact that this clipping: of the fur or hair must be avoided. (therefore in this connection the present invention has as a further iiibject to so construct the cutting); devices oi? the machineas to obviate the shearing cut and provide against cli ppilng oi the -l 'ur or hair.

another object oi? the invention is to provide a foot o ierated inacl'line oi? the class mentioned which, upon actuation of its foot cu erated member, will function automatically to grip and securely hole the for in. position to be cut and then neatly and accurately cut through the same.

in one type of machine of the class above mentioned, the cutter comprises a knife made up of a plurality 0t assembled blade sections disposed with their vertical edges in inutuai contact but free from connection with each other, and it has been found that in such a construction the blades are liable to hecorne separated to agrcater or less dogree as they enter the far with the result that, at the angles of the cutter, the skin and for are liable to become lodged or wedged between the adjacent edges of the blade sec tions thus causing injury to the fur and likewise resulting); in a distortion of the said blade sections. It is therefore another very important object oi the invention to deviate to produce a most effective and accurate severance of the tin-along a zigzag line.

;r nother object of the inventionis to provide novel means for securely gripping and holding the fur while being out which means will function however without any liability oi damaging the fur or distorting the same. i I a In the accompanying drawings:

Figure 5 is a fragmentary front elevation of a type of blade employed in cutting relatively thick furs;

Figure (5 is a similar view illustrating a modified form of blade for employment in (flitting thin furs.

The bed plate oi the machine is indicated springs.

in general by the numeral 1 and the same is reinforced by a marginal depending flange 2 and is supported by corner legs or standards 3 bolted or otherwise secured thereto at their upper ends. Near each end the bed plate is provided upon its upper surface with a boss t from which upstands a post or standard 5 preferably of the cylindrical form illustrated in the drawings, these standarus being perpendicular and parallel to each other and being secured at their lower ends in any suitable manner. The standards are located in a line suitably spaced rearwardly from the forward side of the bed plate 1, and the upper surface of the bed plate forwardly of the said standards is smooth and unobstructed thus providing a surface 6 upon which the fur to be cut may be disposed in a that condition as illustrated in Figures 1 and of the drawings. means being provided for gripping and holding the fur after its disposal upon this surface and for slightly stretching the fur in its laid out condition, and this means will presently be specifically described.

The cutter head of the machine which is indicated in general by the numeral 7 is supported upon and between the standards 5 for vertical movement and the said head comprises a horizontally disposed beam 8 extending between and integrally connected at its ends with the lower ends of sleeves 9 each provided in its upper end with a bushing indicated in general by the numeral 10 and slidably and more or less accurately fitting the respective standard 5. A spring 11 is arranged upon each of the uprights 5 and bears at its lower end against the upper side of the respective boss 4 and is received at .its upper end portion within the lower portion of the respective sleeve 9 and bears against the lower end of the bushing 10, as best shown in Figure l of the drawings. These springs 11 serve to normally yieldably support the cutter head in elevated position and consequently downward movement of the cutter head is against the tension of these In order that such downward movement may be effected under conditions to be later explained, a rocker arm 12 is pivotally mounted between its ends as at 13 upon an upright 14 upstanding from the bed plate 1 in rear ot the cutter head and the forward end of this rock arm coacts with a rounded or conoidal boss 15 formed upon the upper side of the beam 8. A foot lever 16 is supported for rocking movement upon a suitable pedestal bearing 17 beneath the frame of the machine and is provided at its forward end with a foot pedal 18 whereby it may be conveniently rocked, and connected to the rear end of the said foot lever is the lower end of a connecting rod 19 the upper end of which rod is connected with the rear end of the rock arm 12. It will now be evident that upon depression of the foot pedal 18, the arm 12 will be rocked so as to depress the cutter head 7 against the tension of the springs 11 and when the said pedal is relieved of pressure the springs will act to automatically return the cutter head to its elevated position.

In addition to the lJtlIIl 8, the cutter head comprises a beam section 20 adapted to be removably secured to the forward side of the beam 8 by means of stud bolts 21 which are passed through openings in the said beam section 20 and threaded into sockets provided in the said forward side of the said beam 8. Referring now to Figures 2 and I", of the drawings. it will be observed that the forward side of the beam 8 is machined or otherwise provided with a series of substantially V-shaped bosses 23 the relatively angularly disposed faces of which are indicated by the numeral 24 and may form any desired uniform angle with relation to each other depending upon the nature of the zigzag out which it is desired to produce in the fur material acted upon by the machine. Likewise the rear side of the beamsection 20 is provided with a series of substantially V-shaped bosses 2:) designed to match with the bosses 23 whenthe parts are assembled and secured together by the bolts 21. As previously stated the cutting blade of the machine is integral throughout and of zigform comprising a plurality of relatively angularly disposed blade portions. and the said blade is designed to be clamped between the matching edges of the beam S and beam section 20 as best illustrated in Figures 1 and 2 of the drawings.

One type of blade is illustrated in Figure 5 and indicated in general by the numeral 26 and the said. blade comprises a plurality of relatively angularly disposed blade port-ions 27 the angular disposition of which corresponds to that of the faces of the bosses 23 and 2:") so that when, the upper edge portion of the blade is disposed between the beam section 20 and beam 8. it may be securely clamped in position by tightening bolts 21. this portion of the blade being provided with bolt openings 28 for the reception of the said bolts 21. The cutting edge of the blade 26 is indicated by the numeral 29 and the same is formed by bevel-grinding the lower edge of the said blade from both faces as best shown in Figure 4 of the drawings. It will be observed by reference to Figure that the said edge 29 is of undulatory form, the lower points of the edge, indicated by the numeral 30, being inn line with the meeting forward vertical edges of adjacent blade portions 27, and the higher points of the edge, indicated by the numeral 81, being in a line with the meeting rear vertical edges of the said blade portions. It will also be understood and obllu llt

til)

nasaaoo served by reference to the said figure that the points constitute the entering points 01 the cutting cdgeand that these points are successively elevated through the series from one end of the blade to the other so that they successively enter and pierce the skin of the fur to be cut as the blade is moved downwardly through downward movement oi" the cutter head. Not only is the cutting edge 29 oi. umflulatory form as regards the relative vertical disfflacement ot the points 80 and 31 but :lfurthermore the said edge between. each two adjacent points 30 and 31 is more or less scalloped or undulated, as indicated by the numeral. 352, so as to better adapt the edge to cut cleanly through the slain oi. the :lur without any liability of tearing the same. 'llhis type of blade espe cially des' rned for use in cutting relatively heavy furs or in other words turs having comparatively thiclc skins.

.l igure 6 oi the drawings illustrates-i a blade which is especially designed for use in cutting turs having comparatively thin skins and this blade is indicated in general by thenumeral 353, and, like the blade .26, is provided with bolt openings 24 tor the passage oi. the bolts 21. Likewise this blade t(')lll}'ll\l'-I(-)E5 relatively angularly disposed blade portions 35 corresponding to the portions 2%" of the blade 26 and integrally connected at their vertical edges. In this form oi blade the cutting edge is indicated in general by the numeral 36 and is double beveled as in the case of the cutting edge 29. Furthermore the cutting, edge 36, in alternate ones of the blade portions 35, is brought to asharp piercing point 37 located substantially in a line with the meeting torward edges oi adjacent blade portions. lhese particular cutting, edge portions are indicated specifically by the numeral 38 and each is preferably scalloped or undulated, as at 39, and is furthermore extended as at 40 along the vertical edges of the respective blade portions throughout such lengths of these blade portions as project below the lower ed ges ot the intervening or other blade portions. The portions of the cutting edge 36 which are characteristic of the said other or short blade portioi'ns are indicated by the nunieral 4i and are spaced above the cutting edge portions 38 and upwardly inclined and scalloped. or undulacted as at 42, their high points being indicated. by the numeral 4:3 and being, located above the high points of the cuttihg edge portions38 which high points indicated by the numeral 44:. On

the other hand the low points of thecutting, ed e portions 42, which points are indie ad by the numeral 4:5, are located substznitnilly opposite the high points 4d of the cutting J, portions Also in this form of the invention the lower piercing points 37 are -;uceessively elwated throughout theseries so as to successively pierce the skin of the fur to be cut and it will beunderstood that as the blade is lowered. in the cutting op oration. the points 37 will first enter the skin oi. the fur and the cutting edge portions 38 and ll) will make .ii'icisions in the skin after which the cutting edge portions 4-.1 will be brought into action and will complete the severance oi the skin.

in view of the character of the blade employed in the machine it is not required that the blades have any shearing;- coaction with any other part or parts and in tact, for the reasons previously explained, this action is to be avoided, the fur to be out being in tact supported in flat stretched condition in such a manner that the blade, when lowered in the cutting operation, may cut cleanly through the skin of the :turwithout any shearing efl ect. With this end in view the bedplate 1. termed, parallel to its forward side, with a tr:u1sversely extending slot 4:6 which is oi a zigzag}; line oi extent correspmiding to that deliiiied. by the cutting edges of the blades employed in the machine, this slot being located vertically beneath the path oi downward movement of the blade and it and the blade being; relatively pos 1.- tioned, as best illustrated in Figure t, that the blade will enter the slot substantially midway between] the front and rear walls thereof and consequently will have no shearing: coaction with either of these walls. The slot t6 'l'oruied in that portion of the bed plate 1 which bears the surface (3 and consequently the tur to be cut is laid over the slot t6, means being provided as will now be described, tor holding the .fur in a more or less taut conditionwhen so desired.

in order to grip that portion of the fur which is laid upon the surface (3 in rear of the slot all a ipping means provided comprising a pper bar l? provided at its ends with rearwardly extending; arms 48 which are pivotally mounted as at l9 upon cars 50 upon the upper suri'ace ot the bed plate-l. liy a means to be prei-jiently de scribed, the gripper bar 4-7 is normally held in an elevated or upwardly swung); position as shown in Figure l oi the drawings but is adapted to be lowered, upon downward movement of the cutter head, to occupy substantially the positionshown in l igureel of the drawings. lirtliis latter position the arms l8 will seat in suitable depressions 51 provided in the upper surface of the bed plate 1, and the said bar ll will be sin'lilarly receireiil within a depression 52 formed in the said bed plate. The gripper lar t? is provided at the forward side and at its top with a :iorwardly projectii lip 53 in which are lined, theupper ends or piercing pins 54:, the pins, in the lowered position of the gripper bar, being received in openings 55 formed in the bed plate 1 in rear of the slot till Will

46. The openings are arranged in a zigzag line the angles of which extend parallel to the angles of the slot 4C6, and the pins 5% are correspondingly arranged upon the lip 53. i

By reference to Figure 4 it will be observed that when the gripper bar 47 is swung downwardly to its lowered position, the pins 54 will pierce the edge portion of a piece of fur stretched over the surface 6, the fur being in this manner gripped in rear of the slot 46. In order that the gripper bar may be moved downwardly automatically upon downward movement of the cutter head, the cutter head 7 is provided adjacent its ends and at its rear side with downwardly projecting presser feet 56 which bear at their lower ends against bosses 57 provided at the corners between the ends of the gripper bar l7 and its associated arms $8. The presser feet 56 have flat rearwardly presented faces and the parts are so proportioned that in the initial downward move ment of the cutter head 7. the downward movement of the presser feet 56 will act against the bosses 57 to swing the gripper bar 47 downwardly until the bar has assumed substantially the position shown in Figure 4 of the drawings at which time the lower forward corners of the presser feet 56 will have cleared the upper rear corners of the respective bosses 57, and the flat forward faces of the presser feet will pass downwardly in sliding contact with the rear fiat faces of the said bosses, the cutter head 7 being in this manner permitted to have continued downward movement without interference on the part of the gripping device and after the gripping device has been vroughtto position to grip the fur to be cut.

In order that the gripper bar 47 may be swung upwardly to its normal or inactive position upon upward or return movement of the cutter head 7 and also in order that the strip of fur cut from the piece to be pierced by the pins may be strippedfroin these pins, means is provided which will now be described. A stripper bar 58 is disposed beneath the lip 53 and is supported in operative relation thereto by means of pins 59 which are threaded or otherwise secured at theirlower ends, as at 60, in the said bar 58 and are provided at their upper ends with preferably rounded heads 61, the pins working slidably through openings 62 formed in the lip 53. Openings 63 are formed in the stripper bar 58 and receive the piercing pins 54. The pins 59 are of such length that in the elevated position of the gripper bar 47, in which position the heads 61 of the pins rest against the upper side of the lip 53, the stripper bar 58 will occupy the lowered position shown in Figure 1 in which position its under side will be slightly spaced below the piercing terminals of the pins 54:.

It will now be evident. that inasmuch as the pins 59 are freely slid-able through the openings 62, the stripper bar 58 will be moved upwardly when it comes into contact with the fur to he gripped and as the gripper bar a7 is lowered to the position shown in Figure a, so that. the pins 54: will pierce the fur. However, as the gripper bar 47 is swung upwardly, it will be evident that if pressure is exerted in a downward direction against the pins 59, the stripper bar 58 will be moved downwardly over the pins 5% and against the severed strip of fur and will therefore strip the same from the said pins 54:. In order that such pressure may be exerted and also in order that the upward movement of the cutter head 7 will result in the gripper bar 4t7 being elevated to inactive position, presscr fingers 6+1: are pivotally mounted, as at 65. for rocking movement upon the upper side of the gripper bar 4-7, one in front to rear alignment with each of the pins 59 and with the forward end of each linger 6+1: bearing against the head 61 of the respective pin 59. A bar 66 is pivotally connected at its lower end. as at 67. to the rear end of each prcsser finger 64 and the upper end portions of these bars are led through slots 68 formed in the beam 8 of the cutter head 7. pins 69 being fitted through the upper ends of the bars 66 and projecting laterally in opposite directions beyond the same and engaging at their projecting ends against the upper side of the said beam 8. The cutter head 7 moves downwardly through a greater distance than the gripper bar 47 in the operation of the machine and therefore in such operation the bars 66 will remain stationary after the gripper bar 4-7 has assumed the position shown in Figure 4;. and the cutter head 7 will move downwardly along the said bars 66 withoutin any way acting upon. the same. llowevcr as the cutter head 7 is moved upwardly. the upper side of the beam 8 thereof will Hl'lih'o against the projecting ends of the pins 69 thus exertinggf an upward pull against the bars 66 and rocking the presscr lingers 6i upon their pivots so as to cause their forward ends to press d r-.vnwardlv against the pins 59 thus actuating the stripper bar 58 to strip the severed edge of fur from the piercing pins 5%. After the stripper bar 58 has been moved to the limit of its downward movement, the upward pull exerted upon the bars 66 will serve to elevate or swing upwardly the gripper bar 47 until the same has assumed the inactive position shown in Figure l. of. the drawings. It will be understood of course that not. only are the piercing pins 54 arranged in a series extending along a zigzag line corresponding to the line of extent of the slot 46 but also the forward edges of the lip 53 and the stripper bar 58 are similarly formed so that after the liJfr edges of the ki'iite iesaaoo gripper bar 47 has assumed its relative posi tion,: the blades 26 or 33 as the case may be may pass downwardly throiigh the slot 46 without interference on the part of the said gripper bar and its associated parts.

The means just described is adapted, as will be readily understood, to grip the fur in rear of the slot l6, and other means which will now be described is provided for suit ably stretching the fur over the surface .6 and gripping the said iur forwardly or the said slot so that during the cutting operation the fur will be held su'liiciei'itly taut to insure of proper iiassage oi the cutting V therethrough. lhe stretching and gripping means above re- :i'ferredtii comprises spaced arms arranged at the opposite ends of the bed. plate land pivotally .inounted at their rear ends upon pivot screws 71 threaded or otherwise fixed in. the flange 2 at the said ends of the bed. plate. A cross rod 72 connects the forward or outer ends of the arms 70 and serves to relatively brace the arms and. provide for their movement in unison about their pivots 71. A spindlel-l is supported at its ends by the arms 70 immediately inwardly oi the cross rodTQ and extends between the said arms parallel to the said; rod, and this spindle is provided with a covering or sheath 74-. of rubber or any other material toundsuitable for the purpose and constituting a yieldal'ile gripping roll. By means to be presently described the arms 70 are normally held in the upwardly swung or elevated position shown in l igure 1 oi? the drawings but when swung downwardly to the position shown in Figures 2- and 4t oi the drawings, the gripping roll i l designed to cooper ate with a stationary gripping surface 75 1)erpendici'ilarly rounded and i'ormed at the forward side of the bed. plate 1 and. extend ing longitudinally thereo'l, the bed plate be uig provided with a ledge or flange 76 at the bottom Oil the surface 75 and projecting in a forward direction and horizontally disposed. The curvatijire of the surface 75 is approximately on an arc concentric to the pivots 71; and the roll 7% is so positioned that it will have a more or less firm binding action against the surface 75 when. the arms 70 are swiiu'ig down *arclly as stated, it being understood that the fur to be cut, when laid over the sur'liace (i, will l'Je drapeifl also over the space between the surface 75 and flange 7'6, shown. in Figure 1, so that in the downward movement of the arms (0 and in the coaction of the gripping roll with the surface 75, the roll will ride over the fur slightly pulling or stretching the same in a forward direction and binding or gripping the fur against the said surface 75 as best illustrated in Figure 4;. In order that the gripping roll 'i' l may be adjusted so as to adapt it to grip furs. of varying thicknesses or grip a fur of a given thickness with a greater or less degree oi? pressure as may be found desirable, it is pre' 'rable that the ends oi. the spindle 73 of said roll be mounted in the manner shown in Figure 2 of the drawings. in thus mounting the ends of the spindle 73 the said ends'are formed eccentrically upon the inner ends with. cylindrical bearing heads 79 rotatably adjustably mounted in openings 80 formed in the arms 70. Each head 79 is provided. in its outer end )re'lierably with a transverse groove Tl adapting it for the application oli a screw driver whereby it maybe adjusted so as to adjust the respective trunnion 78 and thus vary the position of the axis oli rotation of the spindle 73 with relation to the gripping surface 75. in order that the heads '79 may be retained in place and held in their positions of adjustment, each head is formed with a circumscribing groove 8]., and a set screw 89, is threaded. through the upper side oil." the arm and seats at its inner end within the groove of the respective head and when tightened binds against the bottom wall of the said groove.

in order that the arms "1' 0 and the gripping roll supported thereby may be moved ilownwardly automatically upon downward movemeitit oi the cutterhead 7 and in timed. relation to the downward movement of the gripper bar 45? to active position, pressure test 83 are provided upon the cutter head 7 and 'iroject downwardly t row the torward side thereof near its ends and ride at their lower ends in engagement with bosses Rel formed upon and projecting inwardly from the arms 70 near the pivoted inner ends thereof. Each boss 84.- is 'iorincd with a rounded surface 85 contacting the lower end (it the respective presser toot 83 and the parts are so positioned and pro iiortimied that after the arms 70 have been swung to the :iiull lowered position shown in l igure l, the lower 'lorward corners of the pr er teet 8 55 will clear the upper rear corners or: the bosses 84.- and the pr er leet il may then l'iave continued downward movement without further exerting pressure against the said bosses so that the continued lownward niovc jueut of the cutter head 7 is not iiil'erl erod with. 'lhc arraiwenient is i iirtliermore such that the gripper bar ll and its associated parts will .ie meted downwariillyto gripping position to grip tie rear edge portion oi the fur to be cut prior to actual engagement of the gri Ming roll Telwith the fur and the surface so that the fur is first gripped at re portion. or in. other words rearwardly oi the slot 46, and is immediately subsequently stretched in a iorward direction and. gripped forwardly of the said slot, after which the continued downward movement of the cutter head. 7 brings the cutting edges of theknile ill) into play to sever the fur. In. order that upon upward movement of the cutter head 7 the gripping roll 74 will be returned to its elevated or inactive position as shown in Figure 1, lifting fingers 86 are secured to the rear sides of the presser feet 83 and extend downwardly below the lower ends of the, said feet and forwardly beneath the respective bosses 84; so that upon such movement of the cutter head, the fingers 86 will engage beneath and exert a lifting action against the said bosses 84 for the purpose stated.

By reference to Figure 4 of the drawings it will be observed that the blade is of a thickness considerably less than the width of the slot 46 and that its cutting edge is located substantially longitudinally medially of the slot so that as the cutter head is lowered and the said edge of the blade enters the slot, the opposite sides of the blade will be spaced from the walls of the slot to such an extent that there can be no shearing contact between these parts and,

' permmit of free deflection of the fur by the blade and thus avoid clipping the fur along the line of severance.
